Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed December 18. 1913. Serial No. 806,588.

To all whom. it may concern Be it known that we, CHARLES CHILD andALEXANDER H. Kala, citizens of the United States, both residin at\Vallace, in the county of Calaveras an State of California, haveinvented certain new and useful Improvements in Scrapers; and we dodeclare the following to be a clear, full, and exact description of thesame, such as will enable others skilled in the art to which itappertains to make and use the same, reference. being had to theaccompan ing drawings, and to the characters of reference markedthereon, which form a. part of this application.

This invention relates to improvements in scrapers, the object of theinvention being to produce a scraper used for gradin and leveling whichcan be wheel mounted and controlled to perform its functions in aneffective manner without over exertion on the part of the stock' ortheman operating the same. i Y

A further object of the invention is to produce a scraper which can befilled and emptied easily and rapidly orworked at different positionsaccording as it is to be used for scraping or grading.

Av still further object of the invention is to produce a simple andinexpensive device and yet one which will be exceedingly effective forthe purposes-for which it is designed.

These objects, we accomplish by means of such structure and relativearrangement of the parts as will fully appear by a perusal of thefollowing speci cation and claims.

On the drawings, similar characters of reference indicate correspondingparts in the several views.

Figure 1 is a top plan view of the complete scraper. Fig. 2 is a sideelevation of the same. Fig. 3 is a sectional view taken on a line Y--Yof Fig. 1. Fig. 4 is a fragmentary view, partly in sectlon, showin theconnecting means of the scraper bow with the balance of the structure.Fig. 5 is a sectional view of a spring controlled catch. Fig. 6 is asectional view taken relatively on a line XX of Fig. 5.

Referring now more particularly to the characters of reference on thedrawings, the numeral 1 designates the scraper bowl which is fiat on itsbottom as at 2 and has its upper side and ends shaped in a curved mannerinto a substantial ellipse as at 3, the front end of the bowl beingprovided with a cuttin edge 1.

'lhe numeral 5 designates a disk bolted to the member 1 on each end bybolts 6, each disk 5 having a series of projecting circular bearingmembers 7, 8 and 9 of varying dimensions. Turnably mounted on each ofthe members 7 is a drag bar 10 projecting to the front of the bowl 1 andhaving a cross brace bar 11 and connecting eyes 12 to which may beconnected the draft means. Turnably mounted on the members 8 are thefree ends of a frame 13 which projects to the rear of the bowl 1 and isprovided with a cross bar 14 in which are journaled a pair of supportingswiveled wheels 15. A beam 16 is suitably connected to the membore 13and 1 1 and carries the drivers seat 17. Turnably mounted on each member9 is a bracket 18 which projects to the immediate rear of the bowl 1 andwhere they are provided with bent ends 19 projecting between which is ahandle member 20 riveted thereto by rivets 21, such rivets also securingto the members 19 and 20 a guide member 22 slidable in which is a latch23 connected by a link 24 with an operating handle 25 on the outer endof the handle member 20. Said handle member 20 at its outer end isprovided with a slidable loop 26 for the purpose of receiving a rope 27,ifdesired, for a purpose as will presently appear. The said link 24rojects into the slot 22 of the slotted aide 20 where it is connectedwith the said atch 23, there being a s ring 28 interposed between thelatch 23 an the bottom of the slot 22* to hold the said latch 23 innormal osition. \Vhen in normal position, this atch 23 projects into acatch 29 on the rear of the bowl 1 to hold it in its fixed position asshown in Figs. 1 and 2. \Vhen said latch 23 is in the catch 29, thislocks the bowl in rigid scraping position and then when it is filed withearth and it is desired to empty the same, the handle 25 is operated topull the latch 23 out of the catch 29 and then since the bowl 1 isturnably mounted in the various members described and at a point nearits front end, when it is released, the blade 4 engages the dirt andacts as the load to turn the bowl on its fulcrum point to invertedposition to empty it and then when it has been emptied, it will turn onits curved portion 3 completel around and back intc normal loadingposltion when the latch 23 will again engage the catch 29 and hold it Ifthe entire load is not to be em tied in one spot but is to be s readalong or gradin purposes, the ban le member 20 is lifted which will tiltthe bowl to any degree desired for the purpose of spreading the dirt.Also for gradin purposes, the rope 27 may be used to hold the handlemember 20 at such position as will hold the bowl in a substantiallyperpendicular manner whereby the blade -i will grade and level thesurface over which it is moved.

If it is desired to start the tilting operation of the bowl and handlewithout lifting it by the handle, we provide a pedal 30 on a crank 31journaled on the member 16 and provided on the other side with aprojecting roller 32 adapted, when the pedal 30 is operated. to en a ethe handle member 20 and lift it until the bowl 1 is partly tilted andthen the blade 4 will act as the load to tilt the same to such point asis desired where it will be held by the rope 27.

From the foregoing description it will readily be seen that we have)roduced such a device as substantially ful ls the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice, such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention.

Having thus described our invention what we claim as new and useful anddesire to secure by Letters Patent is 1. A device of the characterdescribed comprising the combination with a wheel mountedframe, of ascraper bowl, 9. projecting bearin member on each side of said bowl,said bearin members being turnably mounted in said rame, another frametumably mounted on said bearing members independently of said wheelmounted frame and of said scraper bowl, a handle member connected tosaid independent frame, a catch carried by said handle member andremovably engageable with said scraper bowl, as described.

2. A device of the character described com rising a scraper bowl, amember fixed rigi ly to each end of said scraper bowl and each having aplurality of projecting circular bearings, a drag frame freely mountedon one pair of said bearings, a wheel mounted frame freely mounted onanother pair of said bearings, a pair of brackets freely mounted onanother pair of said bearings, a handle member on said brackets, aspring controlled latch on said handle member, and a catch on said bowladapted to be engaged by said latch, as described.

3. A device of the character described comprising the combination with awheel mounted frame, of a scraper bowl, projecting bearing members onsaid scraper bowl, such bearing members being turnable in such frame,another frame turnably mounted on said bearing members and independentlyof said wheel mounted frame and said scraper bowl, a handle on saidframe, a catch on said handle removably engageable with said scraperbowl, and a pedal controlled lever on said wheel mounted frameengageable with said handle member to throw the same upwardly, asdescribed.

In testimony whereof we aflix our signatures in presence of twowitnesses.
